ArcTern Targets $400M Climate Fund

ArcTern Ventures is targeting up to $400M for its fourth early-stage fund focused on decarbonisation technologies.

What happened

The Canadian climate investor is seeking institutional capital for a new vehicle backing companies across technologies designed to reduce emissions. The $400M figure is a fundraising target rather than a completed final close.

Why it matters

Climate venture fundraising has become more difficult since the peak of the 2021–22 cycle. Large new specialist funds therefore provide an important signal about whether institutional LPs still have appetite for climate technologies that often require longer development timelines and more capital than conventional software.

The bigger picture

Climate investing is becoming more selective. Capital is increasingly concentrating around specialist managers and technologies with clearer industrial or infrastructure pathways. ArcTern's target suggests large pools of private capital remain available, but managers must make a stronger case around economics, deployment and measurable decarbonisation.
